What does a pedestrian signal with a hand symbol mean?

A pedestrian signal displaying a hand symbol indicates that it is not safe for pedestrians to cross the street at that time. This signal serves as a clear warning to wait until the signal changes, ensuring pedestrian safety during high traffic conditions. The hand symbol effectively communicates to pedestrians that they should remain on the curb and not enter the crosswalk until they see the designated signal indicating it is safe to do so.

The other choices suggest actions or scenarios that are not accurate in the context of what the hand symbol signifies. Crossing at any time, waiting for a green light, or walking quickly all imply that it might be safe to proceed, which contradicts the primary message of the hand symbol that prioritizes pedestrian safety by advising against crossing.
